DTMediaRead Pipe Utility

dt logo 1.5inchThe DTMediaRead SDK now includes a utility called dtmrpipe. This utility allows the user to 'pipe' out uncompressed YUV2 or BGRA video data to another application. It can also be used to pipe an uncompressed stereo audio stream in 16 or 32 bit little endian. This is useful for feeding other applications, such as ffmpeg, with the output of file formats, types or codecs it doesn't support.

 

DTMRPipe

 

DTMRPipe is a command line utility.  The available parameters are:

 

dtmrpipe - pipe raw audio or video out of a media file, by Drastic Technologies (www.drastic.tv)

(c)opyright 1995-2023 Drastic Technologies Ltd. All rights reserved.
Usage: ./dtmrpipe -q -i <sourcefile> -t <type>
    -i <sourcefile> File to decode
    -q Quiet, minimal print outs
    -t <type> Type of raw video or audio:
      Video
         0 BGRA 8 bit
         1 UYUV 8 bit YCbCr 4:2:2
      Audio
         10 16 bit stereo le
         11 32 bit stereo le

 

The basic usage would be

someapp 'parameters for that app' < dtmrpipe cine.cine -q -t 0

The result would be each frame of the cine file would be read and decoded to 8 bit BGRA, and then fed to the secondary encoder.

Examples (using FFMPEG)

 

Convert a cine to a MP4/h.264 (via RGB)

dtmrpipe -i cine.cine -t 0 | ffmpeg -s 1920x1080 -pix_fmt rgb32 -f rawvideo -i pipe:0 -c:v mpeg4 -s 1920x1080 -aspect 16:9 cine.mp4

Convert an MXF (XDcam in this case) to a MP4/h.264 (via YCbCr)

dtmrpipe -i xdcam.mxf -t 1 | ffmpeg -i pipe:0 -pix_fmt yuyv422 -c:v mpeg4 -s 1920x1080 -aspect 16:9 xd.mp4

Convert a DNG Sequence to an MP4/h.264 (via RGB) at 6 megabits

dtmrpipe -i First0000.dng -t 0 | ffmpeg -s 1920x1080 -pix_fmt rgb32 -f rawvideo -i pipe:0 -c:v mpeg4 -s 1920x1080 -aspect 16:9 -vb 6M cine.mp4
